Headaches After New Suspension

[nsta]

Thanks heaps mate. I just checked my rear springs, and to my suprise they are 200.16.006, so only 6kg in the rear, as oppose to the 8kg stated on the website, i will check my fronts tommorow, it will either be 12kg (as website states), or 8kg, like the others on the site, maybe they realised 12/8 is an extreme cambination for r33's?......either way even with 6kg rears, i still get a harsh ride....

Sydneykid, i will get you my coil details tommorow, as they are written on the coil itself, should b easy as.......once you get the details, will the springs you supply(if you do), be a perfect fit for my shocks?

Last question....what does changing spring rates effect, and will it have much impact handling wise?, and will i still have height adjustability?

Front 180.62.012, that means 180 mm free height, 62 mm ID and 12 kg/mm spring rate

Rear 200.62.008 , that means 200 mm free height, 62 mm ID and 8 kg/mm spring

200.16.006 doesn't make sense, is it a typo?

You need to measure the free height and the ID just to be sure. The numbering convention says 200 mm free height and 62 mm (2 1/2") ID. So all I have to do is order some Eibach springs for the rear with the same free height and ID, but wiht a more applicable spring rate, say around 4kg/mm.

The free height difference in the front (180 mm versus 200 mm) can be accommodated in the height adjustment. Which you will have to do anyway as the lower rate springs will compress more with the weight of the car on them.

To answer your questions;

Usually when you use more appropriate spring rates the handling improves, you have more traction as the tyres don't leap from bump to bump, they actually stay on the road.

Yes, the height adjustability stays, just changing the spring rate, that's all.

cheers, will it definitely be the rears that are causing me the problems mate?and since atm the rears are 6kg, putting those to the front and say 4kg to the rears, would that be a good combo?it definitely feels as those the wheels are off the road at certain times, and having set the damper to soft doesnt make much difference.

For what its worth, the damper adjusts both bound/rebound

cheers,

p.s pm me iwth some rough estimates for the rear springs, im in nz btw

thanks

"The free height difference in the front (180 mm versus 200 mm) can be accommodated in the height adjustment. Which you will have to do anyway as the lower rate springs will compress more with the weight of the car on them."

does this mean the new springs will be 200mm height adjustables, like the rears currently, does that mean the car will go lower

If you want it to, yes the springs are shorter by 20 mm.

as long as i can go as low as i can now with my coilovers im happy(just for show days i tend to drop it). The lowest possible setting on the coilovers for the rear, as not very low keep in mind.........so if i can keep the springs the same length, or longer (so i can go lower) that would really help.

cheers

i'll get back to you l8r on about my correct spring rate/id/height

sorry mate, my no's were way off.....and to my suprise, checking my spring rates after pulling out the wheels....here are the figures...

Front: 62.180.014 (no typo here!)

Rear: 62.200.006

That front spring rate is extreme.....

One thing though, even though the rear has more height adjustment then the fronts, the rear doesnt go nearly as low as the front can....is this common with r33's?

The suspension geometry on the rear is the limiting factor. It all turns to shyte when you get it below 340 mm. The front is somewhat more tolerant, the geometry doesn't get too ugly until 325 mm.

please pm me with price quote, those are definitely the right spring rates
